Example

This example will display and change the color of the pen to red of a vector object under pPoint.

L_INT LVectorObject__SetObjectAttributesExample(HWND hWnd, LVectorBase *pVector, LPPOINT pPoint) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
 
   L_INT          nRet; 
   LVectorObject  VectorObject; 
 
   nRet = pVector->HitTest (pPoint, &VectorObject); 
   if (nRet==SUCCESS) 
   { 
      VECTORPEN VectorPen; 
      L_TCHAR szMsg[200]; 
 
      nRet = VectorObject.GetObjectAttributes(NULL, &VectorPen, NULL, NULL); 
      if(nRet != SUCCESS) 
         return nRet; 
 
      wsprintf(szMsg, TEXT("Object Pen Color [%x] -- changing to RED"), VectorPen.NewPen.LogPen.lopnColor); 
 
      VectorPen.bExtPen = FALSE; 
 
      VectorPen.NewPen.LogPen.lopnColor = RGB(255,0,0); 
 
      nRet = VectorObject.SetObjectAttributes(NULL, &VectorPen, NULL, NULL); 
      if(nRet != SUCCESS) 
         return nRet; 
   }
